The woman driving a 2005 BMW suffered “an unknown medical event, causing her to strike a vehicle stopped at the traffic signal on Johnson Road,” said a statement from township police.

Township EMS arrived and found the woman was not breathing, police added. They withheld her name pending notification of family. She was taken to Cooper University Hospital in Camden, where she was listed in stable condition.

A five-year-old child in the BMW’s rear seat was not injured, police said, but was also taken to Cooper as a precaution. They said the driver of the other vehicle involved was also uninjured.

The crash is being investigated by the township police Traffic Safety Bureau.
